FOLDING CHAIR.

SPECIFICATION formingpart of Letters Patent No. 635,486, dated October24, 1899.

Application filed August 26, 1898.

To all whom it may concern:

Be it known that I, HEINRICH LUDWIG CARL FRIEDRICH IHDE, a citizen ofGermany, residing at Hamburg, in the German Empire, have inventedcertain new and useful Improvements in Folding Chairs, (for which I haveapplied for a patent in Germany, dated January 5, 1898, and in France,dated May I, 1898,) of which the following is a specification.

The object of the present invention consists of a chair which withoutthe agency of springs folds together upon being raised by the back andwhich assumes the position of use upon being again placed upon its forelegs.

The chair is specially suited for manufacture on a wholesale. scale inconsequence of its simplicity. It can be made of dimensions suitable forany weight.

Upon the accompanying drawings one form of the invention is shown.

Figure 1 represents a side elevation of a chair in the position of use.Fig. 2 is a side elevation of a chair in the closed position. Fig. 8 isa front elevation of Fig. 1.

As will be seen from the drawings, this chair consists, essentially, ofthe frame 19, connected to the back a, and of the frame 0. A spindle dconnects the frames band 0, forming the legs of the chair, together.These frames are eccentrically pivoted, so that upon raising the part ab the other part 0 extends below the bottom end of the same, Fig. 2.

The seat proper, e, has two pieces of fiat iron are bent into asemicircular form and engage the transverse rods 0 b, and thus hold theseat more securely in connection within the frames 0 and 12 according asthe weight increases.

In addition to the flat irbn pieces mentioned above strengthening-piecesg are fitted to the under side of the seat, and a round angle-rod iispivoted to the strengthening-pieces by Serial No. 689,584:- (No model.)

means of eyelets. The other ends of the rod 1' are pivoted to thespindle (Z.

A chain Z connects the seat with the frame 0, regulating the motion ofthe former. The chain is connected to the transverse piece k of theseat. A rod m strengthens the frame I) and serves as a bearing for therod i.

The action of the chair is as follows: The bent ends of the fiat ironpieces f engage when the chair is in the position of use the transverserods 0 and b of the frames 0 and b. The iron rod 1' transfers the loadof the seat to the spindle d and also to the legs of the chair. Uponraising the chair by the back the ends of the flat iron pieces f arebrought out of engagement with the cross-rods. The seat consequentlyfalls backward and is supported by the iron rod t', and thus preventedfrom falling entirely, resting against the frame b.

In the closed position the chair occupies but little space and by beingsimply placed upon the legs 0 opens out into its position of use.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In a folding chair, the combination of the two leg-frames b and ceccentrioally pivoted together and provided respectively with thecross-rods b and c, of a seat provided with front and rear hooksreversed with respect to each other, and adapted to engage the crossrods respectively, substantially as described.

2. In a folding chair, the combination of the two leg-frames b and c, across-spindle to which said frames are eccentrically pivoted together, aseat, and bent arms 11 and chain by which the seat is connected to thespindle, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.

HEINRICH LUDWIG CARL FRIEDRICH HIDE.
